JOHN C. BELK, OF TOMBSTONE, ARIZONA TERRITORY.

SPECIFICATION forming part of Letters Patent No. seaaza'dated September '7, 1886.

Application filed April 14, 1886. Serial No. 198,826. (No model.)

To aZZ whom it may concern:

Be it known that I, JOHN C. BELK, a citizen of the United States, residing in Tombstone, Cochise county, Arizona Territory, have invented a certain Improved Machine for Gov ering Vire and other Cores, of which the following is a specification.

The object of my invention is to construct a simple and efiicient machine for covering or wrapping wires, strings, and other cores or strands with acovering of wire, fiber, floss, or other flexible material, and also for wrapping or covering compound strings for musical instruments.

In the accompanying drawings, Figure 1 is a side view of my improved apparatus with a part in section. Fig. 2 is a plan view of the same; and Fig. is a sectional view on the line 1 2, Fi 2.

A is a base, on which the different parts of the machine may be suitably mounted, and B is a standard secured to the base, and having bearings for two hollow spindles, I) b, which carry bevcl-pinions a a, forming part of or attached to corresponding disks, D D, on the adjacent faces of the latter. These disks, as hereinafter described, carry on their outer faces the spools or bobbins for the flexible material to be wound onto the central core or strand, which, in the present instance, is shown as drawn from an upright spool, E, on a suitable post, E. The core or strand, on its way to the wrapping-disks D D,passes through a guide-eye, c, on a standard, 0, on the base. In the present instance I have shown each of the disks D 1) as carrying four bobbins, F F;

but the number may be varied, as found convenient. Each bobbin is held between a conical point on the disk and a conical point on a spring tension-arm,f,carried by a bracket, f, which is provided with an adjusting-screw, a, bearing on the arm f, so that more or less tension or friction may be applied to the bobbin F, as the drawing off of the wrapping fibers or strand may require. Each spool has a corresponding guide-pin, (1, adjacent to it,for the passage of the covering-strand around iton its way from the bobbin to be wrapped onto the wire or core from the spool E. Thccore passes directly through the hollow spindles b I), which are in line with each other, and

thence passes through the guide-eye g on an arm, 9, projecting from the standard G, which carries at its upper end a trough, H, provlded with guide-rollers 71/ h, around which the covered wire, as it comes from the second disk, D, may pass and be immersed in parafiine or other insulating material in the trough H when 1t1s desired to apply such material to the covered wireas, forinst-ance, in the case of telegraph wires. In some cases I may also introduce a trough, H, also with guide-rollers, between the two hollow spindles b b, as indicated by dotted lines in Fig. 1, so that the first covering also of the wire may receive a coating before the second covering is applied. From the trough H the wire passes between a pair of feed-rollers, R R, which may be grooved for the reception and passage of the covered wire, and may receive motion, as hereinafter described. I prefer to impart a positive mo tion to the lower roller, R, and have the upper roller, R, a pressureroller, provided with springsr, acting on the movable bearing-blocks r to press the upper roller into contact with the lower one. From the feed-rollers the covered wire passes to a suitable receiving-drum, K, which may receive motion from the shaft of the lower feed-roller, R, by a belt, 7;, or other suitable means. I impart motion to the two wrapping disks D D in opposite dlrcetions by means of a bevel gear -wheel, M, mounted on a shaft, m, in bearings in the standard B atright angles to the two spindles b b. This bevel-wheel M gears into the two pinions a a, and may receive motion either from a hand-crank, N, on the shaft of the wheel M, as shown in Fig. 2, or may be driven by power in any suitable manner. Motion maybe transmitted to the lower feed-roller, R, from the same shaft by means of bevel-gearing p p, shaft P, worm Q, and wormwheel Q on the axis of the lower feed-roller, R.

By the above-described simple construction of apparatus wires or other cores may receive two wrappings laid on in opposite directions, one over the other, with any given number of threads or strands at the same time, and in covering cores for ornamental purposes any desired number of threads of various colors may be used, and prcfe ably a large number of various colors on the first disk and but one or two threads on the second disk, so that the inside covering will show between the threads laid on by the second disk, and thereby pro- I In testimony whereof Ihave signed my name IO duce a Very ornamental variegated cord. to this specification in the presence of two sub- I claim as my inventionscribing Witnesses.
